Great. Now do Guest mode. It's a must-have for places like libraries and internet cafes - if Firefox equalled Chrome in this regard it'd easily gain a percent on the market share scale.
Is Guest mode different from Private Browsing?
In fact - no, it's just a reskin of incognito to make it not feel like you're not watching porn.
Which might make it feel like a non-issue and a useless thing to add, but flip that around - it's a low-cost, potentially very high-reward improvement. It really should've been implemented ages ago.
The only things that need to be changed is the new tab page and the toolbar - both design "improvements".
Sorry, I'm not totally following here.
What is Guest mode, exactly? Esp if not just a containerized session that clears all cookies, history, and personal data when closed.
It literally is just Incognito (Private browsing), a little reskinned. Pretty much a temporary container living as long as the Ghest window - just like Incognito.
